Title: Battery Charging System
IPC: H02J7/00
Filed: 1966-12-08
Abstract: 1,157,129. Battery charging systems. SONOTONE CORP. 8 Dec., 1966 [14 Feb., 1966], No. 55034/66. Heading H2H. A battery 10 of sealed nickel-cadmium cells is charged from a constant voltage source 20 using the control circuit shown in Fig. 1, the battery being in series with an electro-chemical coulometer cell 50 of known type which manifests a sharp voltage change at a predetermined charge input to the battery, to provide a signal which is used to reduce the charging current supplied to the battery. Initially transistors 30, 40 are respectively conducting and cut-off, but upon the production of the coulometer signal transistor 40 conducts to cut-off the transistor 30 and insert a resistor 35 in the charging circuit. A diode 60 provides a discharge current path when a changeover switch S-1 is operated to allow the battery 10 to discharge through a load 100, a diode 62 protecting the coulometer 50 from excessive discharge by commencing to conduct at a predetermined coulometer voltage. In a modification to compensate for the difference between the charging efficiency of the battery and the coulometer, Fig. 6 (not shown), the diode 62 is replaced by a series-connected transistor (120) and resistor (122) which shunt a predetermined charging current from the coulometer. Opposed-parallel diodes (125, 127) connected between the coulometer and battery are added to the circuit in this modification. In the arrangement of Fig. 7, the charging current through the transistor 30<SP>1</SP> is limited by the action of an additional transistor 140 and resistor 138, thus preventing excess current should the charging voltage increase or a battery cell become shorted. In this embodiment the signal from the coulometer causes diversion of most of the current through members 40<SP>1</SP>, 152, 140, 138, with a small amount passing through the coulometer 50 (to maintain its potential) and through the battery 10<SP>1</SP> via the coulometer 50 and members 40<SP>1</SP>, 45<SP>1</SP> ,  30<SP>1</SP>.

Title: Improvements in or relating to reiteration, percussion and speaking tone effects in electronic music generation
Inventor: CAMPBELL DONALD JAMES
IPC: G10H1/26
Filed: 1967-12-04
Abstract: 1,216,080. Electrons musical instruments. CHICAGO MUSICAL INSTRUMENT CO. 4 Dec., 1967, No. 55126/67. Heading G5J. [Also in Division H3] In an electronic music generation system, Fig. 1, signals from single note generators 22, 22a &c., are modified, by sawtooth waves derived from wave shapers 25, driven by a multiphase oscillator 21, to produce percussion and reiteration effects. The modified signals drive tone colour filters 24, are combined on an output line 12 with other signals from conventional sources 11, are amplified at 13 and drive loud-speaker 14. In one embodiment (Fig. 2, not shown), the oscillator (21) is a multivibrator producing a rectangular output in each of two tone generator channels (# 1 , # 2 ), each channel including a wave shaper (25a, 25b) producing sawtooth waves of opposite phase at its terminals, each sawtooth, via an amplitude control circuit 23, determining the amplitude envelope of a signal from a source in the generator channel. These signals are combined in desired phase relationships to give percussion, reiteration, tone colour vibrato and speaking effects. The multivibrator may be free running, keyed by an audio signal at an input (38) or by grounding an alternative input (44), or one shot, keyed at input (38), and the multivibrator frequency may be varied by resistors (45, 46, Fig. 2, not shown). In another embodiment (Fig. 4, not shown) outputs (# 1 , # 2 ) of multivibrator (21) couple, via switches (73, 71) the outputs of tone sources (64, 66) to an amplitude control (23) and at the same time the (# 1  and # 2 ) outputs are coupled by selector switches (68, 70) to a wave shaper (25c). The opposite phase sawtooth outputs at the wave shaper terminals are selectively coupled by a switch (75) to the amplitude control circuit to produce the desired amplitude envelope for the tone signals passed by switches (73, 71) and the amplitude control circuit output drives a single tone colour circuit 24. In a third embodiment (Fig. 5, not shown) an amplitude controlled signal from a single source (83) is selectively applied to tone colour filters (24a, 24b) by switches (81, 82) controlled by the multivibrator (21).

Abstract: 1410673 Bearing Materials CHRYSLER CORP 20 Dec 1972 [27 Dec 1971 (3)] 58882/72 Heading B2E A bearing material comprises a substrate and a working surface layer thereon, the working surface layer comprising a smooth, continuous surface layer of hexagonal crystals of Fe 2 O 3  embedded in a matrix containing iron oxide and an inorganic binder, the crystals having their base planes aligned parallel to the working surface. The working surface layer is preferably porous, the Fe 2 O 3  layer being formed by rubbing the working surface, preferably with heat and pressure. Preferably the substrate is a stainless steel regenerator seal. To form the coating a porous Fe 3 O 4  and FeO layer may be formed on a wrought iron substrate by controlled oxidation then skimming off the top layer of Fe 2 O 3 . A molten Na 2 S binder is then used to impregnate the porous iron oxide before the "break-in" (i.e. rubbing) to form the hexagonal Fe 2 O 3  crystal layer. Alternatively, a mixture of Fe 3 O 4  and binder may be flame or plasma sprayed onto a substrate, or a mixture of Fe 3 O 4  and a leachable substance e.g. NaCl may be flame sprayed onto the substrate before leaching the substance and impregnating with binder e.g. Na 2 S. In the latter case an intermediate layer may be formed by first flame spraying a layer of Fe 3 O 4  without NaCl. The flame sprayed mixtures may contain nickelcoated graphite optionally with boron nitride. Suitable binders are BaSO 4 , CdSO 4 , CaO, Ca 2 P 2 O 7 , CaSO 4 , MnSO 4 , Na 3 PO 4 , Na 2 SO 4 , Na 2 S, Na 2 HPO 4 , ZnS, ZnO, TiO 2 , CaF 2  and NaBO 2 . Example 4 illustrates the use of an alloy of 86% Fe, 4% Cu and 10% C as a substrate which is flame sprayed with a mixture of Fe 3 O 4  and iron before leaching the iron with an electrolytic echant (5% HBF 4  solution) and impregnating with Na 2 S. In operation some Fe 2 O 3  crystals may rub off onto the surface contacted by the bearing material.

Abstract: 1281750 Colour television tubes SONY CORP 22 Dec 1969 [23 April 1969 26 April 1969] 62495/69 Heading HID A colour television tube of the type wherein three electron beams intersect at the centre of a common focusing system, is characterized in that the focusing system comprises a plurality of lenses. In the arrangement shown in Fig. 1 the main focusnig system comprises two equal lenses L m1  and L m2  formed respectively by electrodes G3-G5 and G5-G7. Since the power of the lenses is less than in a single lens system, the aberrations are reduced and also aberrations produced by the first lens L m1  are compensated by equal and opposite aberrations produced by the second lens L m2 . Electrode G5 may be replaced by a diaphragm with a central aperture which limits the sizes of the beams (Fig. 2,. not shown). In another modification (Fig. 3, not shown) the electrode G3 is extended inside electrode G2 by a cup-shaped portion provided with apertures which form individual stops for the beams. The lens system may be extended to include three or four lens components arranged either symmetrically or asymmetrically with respect to the lens centre O (Figs. 4-6, not shown). When the beams are converged at O by an auxiliary lens (Fig. 7, not shown) shown) instead of by the inclination of the cathodes, aberrations caused by the auxiliary lens may be compensated either by making the two lens components of the main focusing lens asymmetrical or by using two symmetrica components but displacing the centre of the system slightly from the point of intersection of the beams.
